Validation of HLT code

Sep23rdReHLTReReco, Sep24thReHLTReReco
  • production details: HLT validation is done on the new menu for 384, reflecting the 2E32 lumi scenario. Two samples were produced using 384patch2; the samples in the Sep24th reprocessing were done with the CMS.GlobalTag GR_R_38X_V12, which includes new EB alignment constants. Full details linked below:

Results

  Release Group
    Egamma Muon Jet MET Tau
  384 Yes / Done Yes / Done Yes / Done Minus Yes / Done

  • egamma (Sam): looked at the Ele12_TightEleIdIsol_L1R, Ele12_TightEle_L1R and Ele22_SW_CaloEleId_L1R; no significant effect observed Unable to compare to other reprocessings due to large differences between trigger menus.
  • muon (Zoltan): results are identical except in the HLT_IsoMu9 path where we see 3 events difference out of 10K, so the changes are OK for Muons.
  • jet (Florent): Trigger performance consistent between sep23rd and sep24th samples, both consistent with Aug13/Sep3 reprocessings.
  • tau (Joshua): agreement in the L2 Efficiencies/Resolution when compared to a photon trigger path is flawless; comparison of specific paths was not possible since the HLT menus were not compatible between the datasets. For what parts of the Tau paths that can be compared between the releases, the results between the Sep3 and Sep23/24 reprocessings are consistent.

Final validation status: Yes / Done

Notes:

  • trigger validation in general is based on automated production of results
    • reports have been formed based on central gui plots (see reports, click on check marks in the table)
    • fast change of some classes of paths in the hlt menu, not reflected in time in offline dqm tags accepted in the release
  • there was a large delay between the announcement of the samples availability by dataops and the time the results became available in gui
  • the request has been re-stated that the results be announced when available to validators (ie harvested and uploaded to dqm gui)
